1. This and several khipu at the MCAP bear the designation CMBE. This is an abbreviation of the name of Oscar Esponey's private collection: Coleccion Manuel Blanco Encalada (named for a 19th century Argentine war hero). The CMBE pieces were donated by Esponey to the Museo Nacional de Historia Natural, but were sent by the MNHN to the MCAP on 25-year loan. This material came from Playa Miller #6.
2. M1 and M2 are composed of a single KB string tied in two places around the primary cord.
